USB thumb drives can be inserted and removed during operation. The inserted USB thumb drive is de-
tected automatically and appears in the Linux directory/media/usbX. When the USB thumb drive is re-
moved, the directory /media/usbX is again removed from the directory structure.
Either the first partition on the USB thumb drive, or, if the memory is not partitioned, the entire memory
will be connected, i.e. the respective directory appears automatically.
The X represents a number from 1 (first USB device) to 8 (last/max. USB device).
The mechanical design of the USB interface is designed to withstand 1,000 plugging and unplug-
ging cycles.
5.2.7. Serial interfaces
The module has two serial communications interfaces (1x RS-232 and 1x RS-485), which are con-
nected via the common RJ45 plug X6.
Maximum baud rate for both interfaces: 115 kBd

The RS-485 interface is “soft” terminated in the dialogue controller with 560 Ω.
If the interface is located at the start or end of the bus topology:
Set switch S3 to ON in order to switch on the 120 Ω terminating resistor.
